Dravidosaurus is a controversial taxon of Late Cretaceous reptiles, variously interpreted as either a ornithischian dinosaur or a plesiosaur. The genus contains a single species, D. blanfordi, known from mostly poorly preserved fossils from the Coniacian of southern India.
Alwalkeria is a genus partly based on basal saurischian dinosaur remains from the Late Triassic, living in India.
The Lance (Creek) Formation is a division of Late Cretaceous rocks in the western United States. Named after Lance Creek, Wyoming, the microvertebrate fossils and dinosaurs represent important components of the latest Mesozoic vertebrate faunas. The Lance Formation is Late Maastrichtian in age, and shares much fauna with the Hell Creek Formation of Montana and North Dakota, the Frenchman Formation of southwest Saskatchewan, and the lower part of the Scollard Formation of Alberta.
The Lameta Formation, also known as the Infratrappean Beds, is a sedimentary geological formation found in Madhya Pradesh, Gujarat, Maharashtra, Telangana, and Andhra Pradesh, India, associated with the Deccan Traps. It is of the Maastrichtian age, and is notable for its dinosaur fossils.
The Twin Mountains Formation, also known as the Twin Mak Formation, is a sedimentary rock formation, within the Trinity Group, found in Texas of the United States of America. It is a terrestrial formation of Aptian age, and is notable for its dinosaur fossils. Dinosaurs from this formation include the large theropod Acrocanthosaurus, the sauropod Sauroposeidon, as well as the ornithopods Tenontosaurus and Convolosaurus. It is the lowermost unit of the lower Cretaceous, lying unconformably on Carboniferous strata. It is overlain by the Glen Rose Formation. It is the lateral equivalent of the lower part of the Antlers Formation.
The Arundel Formation, also known as the Arundel Clay, is a clay-rich sedimentary rock formation, within the Potomac Group, found in Maryland of the United States of America. It dates to the Early Cretaceous, and is of late Aptian or early Albian age. This rock unit had been economically important as a source of iron ore, but is now more notable for its dinosaur fossils. It is named for Anne Arundel County, Maryland.
The Suining Formation is a geological formation in China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. A 2019 paper shows zircon dating of the Suining Formation with a much younger age for the classically thought of Late Jurassic formation; the average age of the dating being roughly 114 myo or late upper Aptian.
The El Collado Formation is a geological formation in Cuenca, Spain whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The El Castellar Formation is a geological formation in La Rioja and Teruel, Spain whose strata date back to the possibly the Valanginian to the Barremian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Blesa Formation is a geological formation in Teruel and La Rioja, Spain whose strata date back to the Barremian of the Early Cretaceous. Dinosaur remains as well as eggs are among the fossils that have been recovered from the formation. Along with the fragmentary anhanguerian pterosaur Iberodactylus. While the lower and upper parts of the formation were deposited in a continental setting, the middle portion of the formation is largely nearshore marine, with remains of plesiosaurs.
The Koum Formation is a geological formation in the North Province of Cameroon, western Africa.
The Mackunda Formation is a geological formation in Queensland, Australia whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. It consists primarily of interbedded and cross bedded greensand, with variably calcareous shale, with local ferricrete.
The El Gallo Formation is a geological formation in Mexico whose strata date back to the Late Cretaceous, from the Santonian to the Maastrichtian. Dinosaur remains are among the fossils that have been recovered from the formation.
The Trichinopoly Group is a geological formation in India whose strata date back to the Late Cretaceous. It lies between the Ootatoor and Ariyalur Groups. It is broad in its southern extremity but thins as it gradually proceeds northwards as it ultimately meets the Ariyalur Group. Dinosaur remains are among the fossils that have been recovered from the formation.
The Cape Sebastian Sandstone is a Mesozoic geologic formation in the state of Oregon in the United States. Hadrosaurid dinosaur remains, such as the sacrum of the Cape Sebastian ornithopod, are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The formation dates to the Campanian stage of the Late Cretaceous epoch.
The Intertrappean Beds are a Late Cretaceous and Early Paleocene geologic formation in India. The beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. The formation spans the Cretaceous–Paleogene boundary, with a stratigraphic range of only a few hundred thousand years before and after the boundary, and a significant debate exists about whether specific sites belong to the Cretaceous or the Paleocene.
The Sierra Perenchiza Formation is a late Campanian to late Maastrichtian geologic formation in Spain. Dinosaur, pterosaur, turtle, lissamphibian, frog and albanerpetontid remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus and the crocodylomorphs Acynodon, Doratodon ibericus and Musturzabalsuchus are also known from this formation.
The Sigou Formation is a Late Cretaceous geologic formation in China. Fossil dinosaur eggs have been reported from the formation, including Dictyoolithus.
Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) and Paleocene Intertrappean Beds of Andhra Pradesh, India. It may be closely related to Sahnitherium. Deccanolestes has been referred to Palaeoryctidae in the past, but recent evidence has shown that it is either the most basal Euarchontan, as the earliest known Adapisoriculid, or as a stem-afrotherian.
The Kallamedu Formation is a Late Cretaceous (Maastrichtian) geologic formation located in the Ariyalur district of Tamil Nadu, India that forms part of the Ariyalur Group. It dates to the Maastrichtian of the Late Cretaceous. Dinosaur remains and petrified wood samples are among the known fossils recovered from this formation.
